BACKGROUND

1. Field of the Disclosure

The present disclosure relates to voice verification in service centers. More particularly, the present disclosure relates to a transparent method and system that registers a voice of a party in order to provide voice verification for communications with a service center.

2. Background Information

Many companies use service centers to provide information and services to callers and customers. Often, a company service center will use voice verification techniques to verify the identity of the caller. Voice verification technology uses human voice characteristics to verify whether a caller is the person that the caller claims to be.

During an enrollment phase, a statistical model of a caller's voice is computed and stored in a database. In the enrollment phase, the caller is requested to train the system by repeating random digits and/or phrases, under the supervision by a representative of the service center. The system then applies statistical learning methods to extract voice patterns of the caller, which will be used in subsequent calls to verify the identity of the caller. Then, during a subsequent call by the caller, the voice characteristics of the caller are compared with the stored voice model. If a match occurs, the system will permit the caller to continue. If no match occurs, the system can either reject the caller or direct the call to an operator. The accuracy of the system is dependent upon the quality of data collected from the caller during the enrollment phase.

For instance, ambient noise at the location of the caller during the enrollment phase may result in interference and a less than optimum voice model of the caller. Additionally, a customer's voice may change over time leading to a voice model that no longer matches the customer. Further, some callers who are cognizant of the enrollment phase may speak using a voice pattern, cadence, or tone not indicative of their ordinary conversational characteristics. All of these factors could lead to a potential future rejection of the caller, necessitating another enrollment phase.

DETAILED DESCRIPTION

In view of the foregoing, the present disclosure, through one or more of its various aspects, embodiments and/or specific features or sub-components, is thus intended to bring out one or more of the advantages as specifically noted below.

According to an aspect of the present invention, a method is provided for registering a voice of a party in order to provide voice verification for communications with a service center. The method includes capturing verbal communication spoken by the party during interaction, initiated by the party, between the party and an agent of the service center. A voice model is created that is associated with the party, in which the voice model is obtained by processing the captured verbal communication spoken by the party. The voice model is stored in order to provide voice verification of the party during a subsequent communication with the service center. The registering is conducted without having notified the party of the registration.

According to another aspect of the present invention, the method includes prompting a requester for information, capturing speech of the requester, processing the captured speech of the requester, comparing the processed speech of the requester with the voice model, and determining whether processed speech of the requester matches the voice model, in which the determination includes determining whether the requester is the party. Additionally, a voice model associated with the requester may be created, in which the voice model of the requester is obtained by processing the captured speech of the requester.

According to another aspect of the present invention, the processed speech of the requester is compared with a second voice model associated with the party. Additionally, according to another aspect of the present invention, the requester is forwarded for further screening when the processed speech of the requester does not match the voice model. The party is serviced when the processed speech of the requester matches the voice model. The voice model associated with the party is updated if it is determined that the requester is the party associated with the voice model, in which the updating includes one of modifying the voice model and replacing the voice model.

According to another aspect of the present invention, capturing the verbal communication includes isolating spoken word of the party from spoken word of the agent. According to another aspect of the present invention, at least one subsequent communication from the party is originated from a location distinct from the origin of the interaction initiated by the party.

According to another aspect of the present invention, creating the voice model includes using one of a Gaussian mixture model, hidden Markov model, machine learning algorithm, maximum entropy model, and support vector machine model. Additionally, voice models from a plurality of callers are collected in order to create a cohort model. The interaction may include, for example, a voice over internet protocol communication, a wireless network communication, and/or a landline communication.

According to still another aspect of the present invention, a system is provided for providing voice registration of a voice of a party to provide voice verification for communications with a service center. The system includes at least one processor configured to capture verbal communication spoken by the party during interaction between the party and an agent of the service center, create a voice model associated with the party from the captured verbal communication, and store the voice model to provide voice verification of the party during a subsequent communication with the service center, wherein the registration is conducted without having notified the party of the registration. The system also includes at least one processor configured to compare captured and processed speech of a requester with the stored voice model and to determine whether the requester is the party. The processor also updates the voice model of the party after a subsequent communication with the party.

According to still another aspect of the present invention, a computer readable medium storing a computer program is provided that registers a voice of a party in order to provide voice verification for communications with a service center. The computer readable medium includes a capturing code segment that captures verbal communication spoken by the party during interaction, initiated by the party, between the party and an agent of the service center, a creating code segment that creates a voice model associated with the party, the voice model being obtained by processing the captured verbal communication spoken by the party, and a storing code segment that stores the voice model to provide voice verification of the party during a subsequent telephone call. The registering is conducted without having notified the party of the registration.

According to another aspect of the present invention a prompting code segment is provided that prompts a requester for information, a second capturing code segment is provided that captures speech of the requester, a processing code segment is provided that processes the captured speech of the requester, a comparing code segment is provided that compares the processed speech of the requester with the voice model, and a determining code segment is provided that determines whether processed speech of the requester matches the voice model, in which the determination includes determining whether the requester is the party.

According to another aspect of the present invention, an updating code segment is provided that updates the voice model associated with the party if it determined that the requester is the party associated with the voice model. At least one subsequent communication from the party is originated from a location distinct from the origin of the interaction initiated by the party.

FIG. 2 shows an exemplary service architecture of the telecommunications system of the present invention. As shown, a user device 201 and a user device 202 are connected to a communications network 215. Either or both of the user devices 201, 202 may be a personal computer, a handheld computer, a desktop computer, a laptop computer, a notebook computer, a mini computer, a workstation, a mainframe computer, a mobile web browser, or a personal digital assistant. The user devices noted herein are used as non-limiting examples; however, with reference to the exemplary embodiment of FIG. 2, the user devices 201, 202 refer to any device with a processor or microprocessor that permits access to a communications network.

The communications network 215 may include, e.g., the public switched telephone network (PSTN), the interne, a satellite communications network, a broadband cable network, a local area network (LAN), a wide area network (WAN), and/or a wireless local area network (WiLAN), including any combination thereof. The networks noted herein are used as non-limiting examples; however, with reference to the exemplary embodiment of FIG. 2, the terms “network” and “networks” refer to any combination of networks that provide a medium for transmitting communications between a processor-based user device and a service center and/or voice response system.

Additionally, a user device 203 and a user device 204 are connected to a communications network 210. By way of example, either or both of the user devices 203, 204 may be a conventional landline telephone, a wireless handset, a portable telephone connected to a base station, an internet-enabled smart telephone, and/or any other device that enables audio communication over dedicated network links. The communications network 210 may include the public switched telephone network (PSTN), an advanced intelligent network (AIN), a personal communications service (PCS) network, a code division multiple access (CDMA) network, a time division multiple access (TDMA) network, a global system mobile (GSM) network, a virtual private network (VPN) that provides secure and encrypted communications between nodes of a broader network, a wireless telephone network and/or any network or combination of networks that provide a medium for transmitting audio communications between a customer device and a service center and/or voice response system.

The service center 250 may include an automatic call distributor (ACD) server (not shown) that routes, e.g., telephone calls to agent 251 of the service center 250. Additionally, the service center 250 may include a router (not shown) that routes packetized data to the agent 251 of the service center 250.

In the embodiment of FIG. 2, the link from the communications network 210 to the service center 250 is, e.g., a landline PSTN link that carries audio communications. Additionally, the link from the communications network 215 to the service center 250 is, e.g., a broadband cable connection. In an alternative embodiment, the links from the communications networks 210 and 215 connects directly to voice response system 260.

The service center includes a voice response system 260 functioning as an agent of the service center. An exemplary voice response system is an interactive voice response system (IVR). An IVR is an automated agent application that collects data from a customer using, e.g., speech recognition, natural language processing, and/or dual tone multi-frequency (DTMF) signals. The interactive voice response unit 260 is programmed to follow a script to collect information from a telephone customer. The script may vary according to the information provided by the customer. Additionally, the interactive voice response unit 260 may be programmed to retrieve and provide information to a customer based upon the information provided by the customer. The retrieved information may relate to products or services in regard to which customers may inquire.

The agent 251 may be a human agent provided with, e.g., a corresponding telephone 254 connected to an ACD server. Each human agent may also be provided with, e.g., a corresponding workstation 257 connected to a router. As an example, the workstations may include an internet browser program that enables communications using an internet network.

Additionally, the agent 251 may be an automated agent program executed by a processor and programmed to collect information from a web customer and/or prompt the customer to provide information to a web user. Alternatively, the agent may be another voice response unit such as an interactive voice response unit.

Although not shown, the voice response unit 260 and the workstation 257 may be connected to internal resources such as a database. The internal resources may contain information related to the products and/or services of the service center 250. Using the internal resources, an agent may appropriately respond to customer requests.

FIG. 3 shows a block diagram of an exemplary voice verification system, according to an aspect of the present disclosure. An incoming call received at the service center 250 is directed to the voice response system 260, using a suitable communications link. Alternatively, the call may be received directly at the voice response system 260. In one embodiment, the voice response system 260 is a voice-enabled and web-enabled contact service center configured to deliver a personalized and natural customer experience. For example, an exemplary voice response system may be included within the AT&T VoiceTone Services Platform. The exemplary voice response system 260 at the service center 250 includes a media server 370 and a content platform 380. The media server 370 is connected to the content platform 380 and communication there between is facilitated via voiceXML (VXML) and hypertext transfer protocol (HTTP), for example, Voice XML 2.0 and HTTP 1.1. Additionally, the voice response system 260 also supports simple network management protocol (SNMP) and primary rate interface (PRI). The media server 370 includes a telephony server 371, a speech recognition server 372, an audio and text to speech server 373, and a network cache 374. The telephony sever 371 includes, for example, a telephony client subsystem, a voiceXML interpreter, and a speech subsystem. The speech recognition server 372 runs, for example, Watson speech recognition software from AT&T. An exemplary audio and text to speech server 373 includes Natural Voices from AT&T. The content platform 380 includes an application server 381, an audio server 382, a database server 383, a remote server 384, a gateway server 385, and an intrusion detection and monitoring system 386. In an alternative embodiment, the voice response system 260 may include only a speech recognition server and a storage for storing voice models.

When a party (party A) contacts (e.g., calls) the service center 250 for the first time, the party is connected with the voice response system 260. It is noted that the present invention is not limited to calls per se, and that any forms of communication are contemplated. For the purpose of illustration, however, a call will be described. An application, or applications, running on the telephony server 371 of the voice response system 260 prompts the party for information such as name, account number, or other personal information. While an automated message may be played to the party indicating that the call may be recorded, as is typical with voice response systems, the party is not notified that their verbal responses will be used to register their voice with the system and create a voice model. Thus, the calling party's normal, natural voice is captured, providing for a transparent voice registration enrollment process. Further, given the automated nature of the system, no supervisory attendant is required in order to capture the verbal responses spoken by the party and to create the voice model. The voice model is a statistical model of the calling party's voice, also known as a voiceprint or voice DNA, which is based on acoustic and linguistic properties.

As the party responds to the prompts, the speech recognition server 372 captures the verbal responses spoken by the party. If the speech recognition server 372 receives the communication between the party and the agent in stereo, then the speech recognition server 372 isolates the channel carrying the speech of the party. If the speech recognition server 372 receives the communication between the calling party and the agent over one channel, then the speech recognition server 372 employs a segmentation algorithm to isolate the speech of the party from the speech of the agent. Thus, only the speech of the party is captured for processing. Exemplary speaker segmentation algorithms include hidden Markov modeling and hypothesis testing.

In one exemplary embodiment, the speech recognition server 372 captures random digits or phrases spoken by the party. In another exemplary embodiment, the speech recognition server 372 captures only certain parts of speech spoken by the party. In any event, the speech recognition server 372 applies an appropriate algorithm to the captured speech of the party to create a voice model associated with the party. Exemplary algorithms employed by the speech recognition server 372 to create the voice model are the any of the Gaussian mixture models, the hidden Markov models, maximum entropy models, support vector machine models, machine learning algorithms, and any other current or future suitable techniques.

It is noted that the speech recognition and verification, may employ either a text independent method or a text dependent method. In one embodiment, a text independent method is used with the present system; although, a text dependent method may be used in an alternative embodiment. The text dependent method requires a speaker to utter keywords or phrases that have identical text for both the recognition and verification processes. On the other hand, the text independent method does not rely upon specific text being spoken. Thus, with the text independent method, a voice model associated with the party is created based upon what is spoken by the party, without performing an intermediate step of speech recognition on predetermined words or phrases.

Once the voice model is created, the voice model is saved with an appropriate identifier to permit access at a later time. The saved voice model is then sent for storage for later retrieval, e.g. at network cache 374, audio server 382, database server 383, remote server 384, gateway server 385, or other suitable storage device. The stored voice model is retrieved, for example, when a voice verification is required, or when a voice model is updated.

For example, when a subsequent contact (e.g., call) is received at the service center by a requester of information or services claiming to be party A, it is necessary to ensure that the identity of the requester is in fact party A. Accordingly, the subsequent call is routed to the voice response system 260. At the voice response system 260, the speech recognition server 372 captures the speech of the caller in the manner discussed previously. Similarly, a voice model of the requester (e.g., second caller) is made using one of the aforementioned algorithms and the is sent to the comparator. At or about the same time, the voice model of party A is retrieved from the storage for comparison. During the comparison process, a processor compares the voice model of party A with the voice model of the requester to determine whether the identity of the requester is party A. The comparison take place at, for example, the speech recognition server 372 or the application server 381. If the requester (e.g., second caller) is determined to by party A, then the requester is served in accordance with their needs. If the requester is determined not to be party A, then the call is either rejected or routed to an attendant for further security screening. Lastly, if the requester is determined to be party A, then the voice model of party A is updated, as will be discussed later.

FIG. 4 shows an exemplary flow diagram showing a method for creating a voice model, according to an aspect of the present disclosure. At step S401, a call from a party is received at the voice response system 260 of the service center 250. For example, the party may be calling to request information regarding their account, a service, a product, etc. In an exemplary embodiment, the voice response system 260 (e.g., agent) of the service center 250 interacts with the party. At step S402, the voice response system 260 prompts the party for information such as name, account number, etc. Again, the party is not notified that their verbal responses will be registered with the system to provide voice verification associated with future calls to the service center. While an automated message may be played to the indicating that the call may be recorded, as is typical with voice response systems, for example, in order to ensure quality control, the party is not notified that their verbal responses will be used to register with the system and create a voice model. Thus, the party's normal, natural voice is captured as a result of the transparent voice registration enrollment process. At step S403, the speech recognition server 372 captures speech of the party in response to the prompts. As discussed above, if the speech recognition server 372 receives the communication between the party and the agent in stereo, then the speech recognition server 372 isolates the channel carrying the speech of the party. If the speech recognition server 372 receives the communication between the party and the agent over one channel, then the speech recognition server 372 employs a segmentation algorithm is employed to isolate the speech of the party from the speech of the agent. Thus, only the speech of the party is captured for processing.

At step S404, the speech recognition server 372 applies an appropriate algorithm to the captured speech of the party to create a voice model. Exemplary algorithms employed by the speech recognition server 372 to create the voice model are the any of the Gaussian mixture models, the hidden Markov models, maximum entropy models, support vector machine models, machine learning algorithms, and any other current or future suitable techniques. At step S405, the voice model is saved with an appropriate identifier to permit access at a later time.

FIG. 5 shows an exemplary flow diagram for comparing a requester's spoken word to a voice model and determining whether a match exists, according to an aspect of the present disclosure. At step S501, a call from a requester is received at the voice response system 260 of the service center 250. For example, the requester may be calling to request information regarding their account, or other information where it is desirable to confirm the identity of the requester. In an exemplary embodiment, the voice response system 260 of the service center 250 interacts with the requester. At step S502, the requester requests access to, for example, account information. The voice response system 260 prompts the calling party for information such as name, account number, etc. At step S503, the speech recognition server 372 captures speech of the calling party in response to the prompts. As discussed above, if the speech recognition server 372 receives the communication between the requester and the agent in stereo, then the speech recognition server 372 isolates the channel carrying the speech of the requester. If the speech recognition server 372 receives the communication between the requester and the agent over one channel, then the speech recognition server 372 employs a segmentation algorithm is employed to isolate the speech of the requester from the speech of the agent. Thus, only the speech of the requester is captured for processing.

At step S504, the speech recognition server 372 applies an appropriate algorithm to the captured speech of the requester to create a voice model. Exemplary algorithms employed by the speech recognition server to create the voice model are the any of the Gaussian mixture models, the hidden Markov models, maximum entropy models, support vector machine models, machine learning algorithms, and any other current or future suitable techniques. Alternatively, the captured speech of the requester may be processed in any manner in order to permit comparison with the voice model of party A, without the creation of a voice model. At step S505, the voice model of the requester is saved, for example at the network cache 374, the database server 383, or other suitable storage.

At step S506, a determination is made as to whether the requester is the person who they are representing to be, e.g. party A. That is, a comparison is made between the voice model of the requester and the voice model of party A. The comparison is performed using, for example, one of the aforementioned modeling techniques, and is performed at the speech recognition server 372, the application server 381, or other suitable location. If the voice model of the requester matches the voice model of party A (step S506=YES), then the processing of the call continues and the caller is serviced at step S507. If the voice model of the requester does not match the voice model of party A (step S506=NO), then the call is rejected at step S510. In this case, the call is routed to an automated or live agent 251 for further security screening at step S511. As discussed, the speech of the requester is captured and a voice model is created before it is compared to a stored voice model. As alluded to, in another embodiment, the captured speech of the requester is compared to a stored voice model without first creating a voice model associated with the requester. In this embodiment, the captured speech of the requester is processed in any known manner in order to facilitate comparison with the voice model of party A.

Additionally, at step S508, the voice model associated with the party is updated to include any new voiceprint information from the present call. In this regard, the voice model may be either updated or entirely replaced. Thus, with every subsequent call from a particular party, the party's voice model is automatically updated. Alternatively, a check may be performed of the voice model associated with the party, such that the voice model would only be updated if there is a distinction between the new voiceprint information and the voice model. In this fashion, the party's voice model stays current should there be any change in the party's voice, or should the party call from multiple location having differing ambient background noise. Thus, the automatic updating of the system ensures an adaptive system that improves over time. Alternatively, the system may store multiple voice models of a party, such that when a requester contacts the service center, the comparison at step S506 is performed with the voice model of the requester and the multiple voice models of a party, in order to determine whether any match exists.

Accordingly, the present invention enables an organization to provide voice verification services associated with callers to a service center 250. The present invention eliminates the need for customers to train the voice response system, since the enrollment phase is transparent to the party. Since the system is transparent, the present invention reliably creates a voice model of a party, without the party intentionally or subconsciously changing their voice during the enrollment phase. Further, the present invention provides that the party's voice model is updated with each subsequent call of the party, such that the stored voice model will include changes to the party's voice over time, and calls from different locations having various ambient background noise. Additionally, according to an alternative embodiment, voice models from a plurality of callers may be collected to create a cohort model, which may be used during the verification process.

What is claimed is:
 1. A method comprising: receiving a communication from a party at a voice response system; capturing speech spoken by the party during the communication; creating, with a processor, a voice model of the party, the voice model being created by processing the speech; and storing the voice model to provide voice verification during a subsequent communication, wherein the voice model is created without notifying the party.
 2. The method according to claim 1, further comprising: receiving a communication from a requester requesting access to an account; prompting the requester for information; capturing speech of the requester; processing the speech of the requester to create processed speech; and comparing the processed speech of the requester with the voice model.
 3. The method according to claim 2, further comprising determining whether the processed speech and the voice model are a match.
 4. The method according to claim 3, further comprising granting access to the account when the processed speech and the voice model match.
 5. The method according to claim 3, further comprising denying access to the account when the processed speech and the voice model fail to match.
 6. The method according to claim 3, further comprising screening the requester when the processed speech and the voice model fail to match.
 7. The method according to claim 3, further comprising automatically updating the voice model when the processed speech and the voice model match.
 8. The method according to claim 1, wherein the capturing comprises isolating the speech of the party via a segmentation algorithm.
 9. The method according to claim 2, wherein the information comprises account information.
 10. The method according to claim 2, further comprising automatically updating the voice model with new voiceprint information.
 11. A system comprising: a memory that stores executable instructions; a processor that executes the executable instructions; wherein the system receives a communication from a party, captures speech spoken by the party during the communication, creates a voice model of the party by processing the speech, and stores the voice model to provide voice verification during a subsequent communication, wherein the voice model is created without notifying the party.
 12. A tangible computer-readable storage medium encoded with an executable computer program for registering a voice of a party in order to provide voice verification and that, when executed by a processor, causes the processor to perform operations comprising: receiving a communication from a party at a voice response system; capturing speech spoken by the party during the communication; creating, with a processor, a voice model of the party, the voice model being created by processing the speech; and storing the voice model to provide voice verification during a subsequent communication, wherein the voice model is created without notifying the party.
 13. The tangible computer-readable storage medium according to claim 12, further comprising: receiving a communication from a requester requesting access to an account; prompting the requester for information; capturing speech of the requester; processing the speech of the requester to create processed speech; and comparing the processed speech of the requester with the voice model.
 14. The tangible computer-readable storage medium according to claim 13, further comprising determining whether the processed speech and the voice model are a match.
 15. The tangible computer-readable storage medium according to claim 14, further comprising granting access to the account when the processed speech and the voice model match.
 16. The tangible computer-readable storage medium according to claim 14, further comprising denying access to the account when the processed speech and the voice model fail to match.
 17. The tangible computer-readable storage medium according to claim 14, further comprising screening the requester when the processed speech and the voice model fail to match.
 18. The tangible computer-readable storage medium according to claim 14, further comprising automatically updating the voice model when the processed speech and the voice model match.
 19. The tangible computer-readable storage medium according to claim 12, wherein the capturing comprises isolating the speech of the party via a segmentation algorithm.
 20. The tangible computer-readable storage medium according to claim 13, further comprising automatically updating the voice model with new voiceprint information.
